The effect of a variety of low power plasma treatments on low modulus carbon fibre surfaces have been examined using X-ray photoelectron spectroscopy. Plasma treatments were carried out in an insitu plasma cell which was attached to a PHI 5400 X-ray photoelectron spectrometer. This enabled the immediate effects of the plasma to be studied before the treated surface was exposed to air. Air plasmas introduced both alcohol and carboxyl groups onto fibre surfaces. Nitrogen plasmas gave very similar results to ammonia plasmas with the formation of three nitrogen containing species on he fibre surface.
